I struggle to find food I like?

So what if you don't like chocolate, cheese and biscuits? Surely that's a good thing?! You should focus less on whether you like silly things like shop bought sandwiches and focus more on weather you like HEALTHY foods. You should make an effort to 'try' as many fruit and vegetables, fish, lean meat, healthy dairy etc as possible. Who cares if you don't fancy the taste of unhealthy food!
